GAS-BURNER.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed May 26, 1906. Serial No. 318,887.

To all whom it may concern:

Be it known that I, AUGUSTUS F. THOMP- SON, a citizen of the United States, residing at Huntin ton, in the county of Cabell and State of Fest Virginia, have invented new and useful Improvements in Gas-Burners, of which the following is a specification.

My invention relates to gas burners, and its primary object is to provide a novel and highly useful device of this character which is adapted to be used in connection with gas grates, heating and cooking stoves, steam boilers, hot air furnaces and kilns, one wherein the air and gas are so thoroughly intermixed before entering the burner proper that perfect combustion may be produced, one which may be manufactured and sold at a comparatively low cost, and one which will produce an intense heat with the use of a minimum amount of gas.

A further object is to provide a device of the character stated with a plurality of mixing tubes which unite the burner proper and gas sup ly pipe.

A sti further object is to provide a device of the character stated which is provided with means for regulating the amount of air entering the mixing tubes in order to accommodate for different pressures under which gas is supplied to the burner.

With the above and other objects in view,

.the invention consists of the construction,

combination and arran ement of parts hereinafter fully describeii claimed and illustrated in the accompanying drawings, wherein- Figure 1 is an elevation of a burner constructed in accordance with my invention, portions thereof being in vertical section.

ig. 2 is a section on the line 22 of Fig. 1. Figs. 3, 4: and 5 are transverse sections of modified forms of the burner proper, and Fi 6 is an elevation of the mixing tubes an gas supply pipe, one of the mixing tubes and a portion of the gas supply pipe being in vertical section, this figure illustrating the means by which the amount of air entering the mixing tubes may be regulated.

Referring to the drawings by reference numerals, and particularly to Figs. 1 and 2, 2 designates the burner proper which comprises a tubular member fully open at its ends. The u per surface of the burner 2 is provided wit a plurality of openings 3, through which the admixture of air and gas escapes to be consumed, and with a plurality of openings 4, which are surrounded by depending sleeves 5. The upper ends of the mixing tubes 6 are positioned and removably secured within the sleeves 5 by set screws 7. The lower ends of the tubes are provided with transversely alined openin s 8 to receive a gas supply pipe 9. The supp y pipe is provided with openings 10 which are located in those portions of the pipe surrounded by the mixing tubes and through which the gas escapes into the mixing tubes, wherein it is thoroughly intermingled with air entering the tubes through transverse alined openings 11.

In order to adapt the burner for use in connection with gas grates having the gas mains leading into the center or from one of its ends thereof, I have found it desirable to construct the gas supply pipe 9 in two sections and connect the sections by a coupling 9 to permit the application of a gas cook 9 and to thread one end of the supply pipe. The other end of the gas supply pipe is closed by a removable cap 12. To provide means by which the burner may be secured in applied position, I have secured to the burner proper clips 13, as fully disclosed in Fig. 2 of the drawings.

Inasmuch as the mixing tubes 6 are connected to the supply pipe 9, it is only necessary to use two set screws to secure the burner proper to the mixing tubes.

In Fig. 3 I have shown the slightly modified form of the burner proper, and in this instance the burner 2 isprovided with a flat angular surface 14% wherein are located the openings 8.

In Figs. 4 and 5, I have illustrated the preferred modified forms of the burner without the sleeves 5, and in these instances, the upper ends of the mixing tubes 6 may engage directly in the openings 4.

In Fig. 6 of the drawings, I have illustrated the mixing tubes provlded with means by which the amount of air entering them may be regulated in order to accommodate for the various pressures of gas supply, this means consisting of sleeves 15 revolubly mounted upon the mixing tubes and provided with openings 16 which may be either partially or fully alined with the openings 11 to regulate the amount of air entering the mixing tubes or thrown out of registration therewith to fully close the openings 11 to prevent air entering the tubes.

Having fully described and illustrated my invention, what I claim is:

A gas burner comprising a horizontal burner tube and open at both erds and pro- 5 vided at intervals 1n its length with jet perforations, a plurality of mixing tubes discharging into said burner tube at intervals in the length thereof and each provided with one or more air intake openings, and a hori- 10 zontal gas supply pipe passing successively through alined transverse openings in the mixing tubes below the air intake openin and having gas discharge ports protective y arranged within such mixin tubes. f

In testimony whereof, I a x my signature 15 in presence of two witnesses. e
